Favor or Favour? Which Spelling Is Correct?

You are writing an email, school assignment, or professional message when you suddenly pause: should it be favor or favour?

Both spellings are correct, but the right choice depends on the type of English you are using.

Favor is the standard spelling in American English, while favour is used in British English and other varieties influenced by British spelling.

They have the same meaning and pronunciation, so the difference is mainly regional spelling.

This small difference can be confusing, especially when you read websites, books, or messages from different countries. 

You may also see related forms such as favorite/favourite and favorable/favourable, which follow the same spelling pattern.

In this guide, you will learn when to use favor or favour, see clear examples, and discover an easy way to remember the difference.

Quick Answer

Favor is the standard American English spelling, while favour is the standard British English spelling. Both words have the same meaning and pronunciation. The main difference is the letter u. U.S. writers normally use favor, while British writers use favour.

For example:

• American English: Can you do me a favor?
• British English: Can you do me a favour?

Neither spelling is wrong. The correct choice depends on the variety of English you are using.

Quick Rule

What Is the Difference Between Favor and Favour?

Favor and favour have the same meaning, but they belong to different English spelling systems. Favor is used in American English, while favour is used in British English and other varieties that follow British spelling conventions.

The difference is simply the letter u.

American English

favor

British English

favour

For example:

Could you do me a favor?

This is the standard American spelling.

A British writer would normally write:

Could you do me a favour?

The meaning does not change.

The word can be used as both a noun and a verb.

As a noun, favor or favour can mean help, support, approval, or a small gift.

As a verb, it can mean to support, prefer, or give an advantage to someone or something.

Cambridge lists these meanings for both forms and identifies the spelling difference as a U.S.-British variation.

Is Favor the American Spelling?

Yes, favor is the standard American English spelling. If you are writing for readers in the United States, favor is normally the preferred form. American English removes the u found in the British spelling favour.

Examples include:

• Do me a favor.
• She asked me for a favor.
• The decision went in his favor.
• I am in favor of the proposal.
• The evidence appears to favor one explanation.

These examples use the standard American spelling.

The same word appears with a u in British English:

• Do me a favour.
• She asked me for a favour.
• The decision went in his favour.
• I am in favour of the proposal.
• The evidence appears to favour one explanation.

The meaning remains the same.

If your website targets a U.S. audience, using favor consistently is the better choice.

Is Favour the British Spelling?

Yes, favour is the standard British English spelling. British English normally keeps the u in words such as favour, colour, and honour.

For example:

Could you do me a favour?

A British reader will recognize this as the standard spelling.

You may also see:

• in favour of
• favourable
• favoured
• favouring

These forms follow the same British spelling pattern.

In American English, they usually become:

• in favor of
• favorable
• favored
• favoring

Grammarly notes that American and British English have several spelling differences involving -or and -our endings. Words such as color/colour, honor/honour, and favor/favour follow this pattern.

Favor or Favour: Comparison Table

American English	British English	Meaning
favor	favour	Support, approval, help, or preference
favorable	favourable	Positive or helpful
favored	favoured	Preferred or given an advantage
favoring	favouring	Supporting or preferring
favorably	favourably	In a positive way
favorite	favourite	Most liked or preferred

The main spelling pattern is easy to see.

American English usually uses -or.

British English usually uses -our.

However, you should not assume that every word ending in -or changes to -our in British English. English has exceptions, so individual words should be checked when you are unsure.

Favor and Favour Have the Same Meaning

Favor and favour are not different words with different meanings. They are spelling variants used in different varieties of English. Changing the spelling does not change the basic meaning.

For example:

She asked me for a favor.

And:

She asked me for a favour.

Both sentences mean that she asked someone to help her.

The only difference is the spelling convention.

The same applies to:

The decision was in his favor.

and:

The decision was in his favour.

Both mean that the decision benefited or supported him.

This is an important point because some readers may think the u changes the meaning.

It does not.

The difference is regional spelling.

Why Does American English Use Favor?

American English uses favor without the letter u as part of a broader spelling pattern that distinguishes many American spellings from British ones. Similar differences appear in words such as color/colour and honor/honour.

The shorter American forms became established through changes in American English spelling.

Noah Webster played an important role in promoting distinctive American spelling conventions. His dictionaries influenced American written English and helped establish forms that differed from British conventions.

However, it would be too simple to say that Webster personally created every American spelling difference.

The history of English spelling developed over a long period.

Grammarly explains that words such as color, favor, and honor use the shorter -or spelling in American English, while British English uses colour, favour, and honour.

The result is the spelling difference we see today:

American: favor

British: favour

Favor vs Favour: Which One Is More Correct?

Neither spelling is universally more correct. Favor is correct in American English, while favour is correct in British English. Your choice should match the English variety and audience you are writing for.

If you are writing for an American audience, use:

favor

If you are writing for a British audience, use:

favour

For example, a U.S. business email might say:

Could you do me a favor?

A British email might say:

Could you do me a favour?

Both are grammatically correct.

The important thing is consistency.

If you choose American English, avoid switching between favor and favour without a reason.

Favor and Favour in Common Expressions

The spelling difference appears in many common phrases.

American English:

The phrase means asking someone to help you.

The meaning is the same.

Again, only the spelling changes.

Favor, Favour, and Related Words

British:

favour

Favorable vs. Favourable

American:

Favorite or Favourite?

Favorite and favourite follow the same American-British spelling difference. American English uses favorite, while British English uses favourite.

For example:

American:

British:

Blue is my favourite colour.

Notice that both words change in the British sentence.

favorite → favourite

color → colour

This is useful because readers often encounter these words together.

Cambridge Dictionary identifies favorite as the U.S. spelling of favourite.

So if you are writing in American English, use:

favorite

If you are writing in British English, use:

favourite

Common Mistakes With Favor and Favour

The most common mistake is not choosing the wrong spelling. It is mixing American and British spelling styles in the same piece of writing.

Mistake 1: Mixing favor and favour

For example:

My favorite color is blue, and I asked him for a favour.

The sentence is understandable.

However, it mixes American favorite/color with British favour.

If you are following American English, write:

My favorite color is blue, and I asked him for a favor.

If you are following British English, write:

My favourite colour is blue, and I asked him for a favour.

Consistency makes your writing look more polished.

Mistake 2: Thinking favour is incorrect

Favour is not incorrect.

It is the standard British spelling.

If you see favour in a British newspaper or book, the spelling is not a mistake.

Mistake 3: Thinking favor is incorrect

Favor is not incorrect.

It is the standard American spelling.

If you are writing for U.S. readers, favor is the normal choice.

Mistake 4: Changing the spelling in a quotation

If you are quoting a source, do not automatically change its spelling.

For example, if a British source uses favour, keep the original spelling when quoting it.

The same applies to American sources using favor.

This helps preserve the original wording.

How to Remember Favour vs Favor

A simple memory trick is to connect favor with other common American spellings.

American English

favor

color

honor

British English

favour

colour

honour

Think:

American English drops the U.

This is not a rule for every English word.

But it works for this group of common words.

Another useful trick is to remember the phrase:

American = favor

British = favour

If your target audience is in the United States, choose the shorter spelling.
